Sharks

Sharks (superorder Selachimorpha) are a type of fish with a full cartilaginous
skeleton and a highly streamlined body. The earliest known sharks date from more
than 420 million years ago. Since that time, sharks have diversified into 440
species. They range in size from the small dwarf lanternshark (Etmopterus
perryi), a deep sea species of only 17 centimetres (6.7 in) in length, to the
whale shark (Rhincodon typus), the largest fish in the world, which reaches
approximately 12 metres (39 ft).

Despite its size, the whale shark feeds only on plankton, squid, and small fish
by filter feeding. Sharks are found in all seas and are common down to depths of
2,000 metres (6,600 ft).
